The total capacity of the 6 cell battery pack is 10200mAh and it only weighs 381g, including the high-quality neoprene pouch.
The bicycle light battery has three layers of physical protection:
Heat shrink wrapped for water and dust proofing,
Rubber enclosure for added water-, dust- and shock proofing, and
A stretchable neoprene pouch as the final layer of water-, dust- and shockproof.
The included Neoprene Pouch is non-slip so will not vibrate and let dust scratch your frame, like the older nylon pouches used to do. You can mount the battery on virtually any part of your bicycle, such as:
the stem,
the handlebar, or
the top tube.
Short cable - only 20cm from your battery to plug. No need to wrap your cord 10 times around your handlebar to get rid of all the extra cable anymore.
